# SDL\_HINT\_JOYSTICK\_LINUX\_DIGITAL\_HATS(3)

A variable controlling whether joysticks on Linux will always treat 'hat' axis inputs (ABS\_HAT0X - ABS\_HAT3Y) as 8-way digital hats without checking whether they may be analog.

## NAME

SDL\_HINT\_JOYSTICK\_LINUX\_DIGITAL\_HATS - A variable controlling whether joysticks on Linux will always treat 'hat' axis inputs (ABS\_HAT0X - ABS\_HAT3Y) as 8-way digital hats without checking whether they may be analog.

## HEADER FILE

Defined in SDL3/SDL\_hints.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**#define SDL\_HINT\_JOYSTICK\_LINUX\_DIGITAL\_HATS** *SDL\_JOYSTICK\_LINUX\_DIGITAL\_HATS"*

## DESCRIPTION

The variable can be set to the following values:

• "0": Only map hat axis inputs to digital hat outputs if the input axes\
   appear to actually be digital. (default)

• "1": Always handle the input axes numbered ABS\_HAT0X to ABS\_HAT3Y as\
   digital hats.

This hint should be set before a controller is opened.

## AVAILABILITY

This hint is available since SDL 3.2.0.
